REB Interface Module

The CFM series REB interface module features a complete filtering Ethernet bridge.
The REB module terminates any capacity of 2-4-6-8 Mbps from the multiplexer on a
single 10 Mbps 10Base-T UTP Ethernet port.
REB Interface Module LEDs
There are two groups of LEDs on the front of the module:
• LAN: Rx, Tx
• WAN: Rx, Tx
Green color of the LED indicates activity.
Red color of the LAN Tx LED indicates the absence of the LAN link signal on the
Ethernet.
Red color of the LAN Rx LED indicates LAN collision in case if Ethernet port of the
REB module operates in Half Duplex mode.
The REB module has a connector and a jumper onboard marked with "JMP" and the
reset button to restart the Ethernet bridge.
The reset button may useful for testing purposes.
Both the jumper and the connector are used for production and are not configurable.
The switching between Fdx and Hdx port modes can be accomplished as follows:
• From Telnet or ASCII terminal it can be accomplished using "Mod # setbridge
{Hdx|Fdx}" command line (Chapter 4.4.3).
• From IDU LCD: Press "ENTER" to enter setup mode → select "Modules" → select
"Module # Bridge" → select "Bridge Interface" → "Change FDX/HDX", choose the
mode and confirm as prompted
